' MARKING DEVICE FOR WRAPPING MACHINES Filed Oct. 19.192?

Patented June 23, 1931 U Eo-srATEs PATENT OFFICE HENRY E. GOERKE, OF FLORAL PARK, NEW YORK, ASSIGNOR TO AMERICAN MACHINE & FOUNDRY COMPANY, A CORPORATION OF NEW JERSEY MARKING DEV-ICE FOR WRAPPING MACHINES Application file d" October 19, 1927. Serial No. 227,126.

This invention relates to a marking device for wrapping machine's, its main object being to puficture the wrapper for each package as the paper is fedin strip form tothe wrapping mechanism, with a distinguishing mark which may be changed daily or at any other desired time interval, so that the age of the package can thereafter be easily ascertained by one familiar with the code.

An advantage of combining the marking device with the paper feeding mechanism instead of associating the same with the package conveyor, as has been done before, is that only one marker is required when puncturing the paper before wrapping, whereas as many markers as there are-package spacers on the conveyor are needed when marking the finished package as it is carried away from the wrapping mechanism.

The present marking device includes an arm adapted to carry interchangeable plates having different combinations of marking pins, and a resilient stripper which is pressed against the paper while the marking pins penetrate the same and which has a plurality of holes corresponding to the various positions of the marking pins on the different marking plates. The marking arm and stripping spring are removably attached to an oscillatory sleeve mounted on the rock shaft of the paper feed mechanism which carries the means for clamping the paper upon its support when the strip of paper is not feeding and a wrapper is being cut therefrom; and the perforated paper support is fastened to the table which supports the fed paper on its way to the wrapping mechanism. When the paper clamp is operated, its actuating lever, which in its rest position bears against a stop fastened to the marker carrier sleeve, releases the sleeve and permits a spring to actuate the marking device. With the object of producing a machine of the character just described, and with other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then set forth in the claims hereunto appended.

50. In the accompanying drawings, in which lik elcharacters of reference indicate the same 'orl-i'ke parts, Fig. 1 is a plan view of a portion of the paper feeding mechanism of a wrapping machine, equipped with air-improved marking device; Fig. 2 is a cross-sectional view of the marking'device taken on the line 22 in Fig. 1 when at rest in its rest position; Fig. 2 is a cross-sectional view of the marking device in the depressed or marking position; and Fig. 3 is a side elevation of the paper feeding mechanism shown in Fig. 1, showing the operating mechanism of the marking device.

In carrying the invention into effect, there is provided paper feeding mechanism of a wrapping machine of well known construction and operation, and means controlled by said mechanism for marking paper fed to it. The wrapping machine referred to is disclosed in the patent to Armstrong, No. 1,626,- 379, granted April 26, 1927. In the patent, the equivalent of the present table 4 is marked 125, and the equivalent of the present rockshaft 6 is marked 161. In the best constructions contemplated, the marking means is spring-actuated and is controlled by the controller of the paper clamp of the paper feeding mechanism. These parts may be varied in construction within the scope of the claims, for the specific device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention therefore is not to be restricted to the precise details of the structure shown and described.

Referring to the drawings, which is fed in the direction over the table 4, passes beneath an arm 5 mounted on a shaft 6 operated by a lever 7 controlled by abar 8 and a spring 9, the arm 5 being eld away from the paper when the bar 8 is at rest and being pressed down upon the paper by the action of the spring 9 when the bar 8 is moved in the direction of the arrow by the action of the wrapping mechanism controlling the paper feed.

Upon the shaft 6 is loosely mounted a sleeve 10, to which is fastened a block 11 and a flattened collar 12. The block 11, which is held on the sleeve 10 by means of the paper P,

of the arrow a set screw 13, carries a marking device including an interchangeable marker plate 14, of which a number corresponding to the diffcrent date markings are used, and including also a stripping spring 15. The marker plate 14 carries marking pins 16, the number and arrangement of which indicate the different date markings, and it is attached to the block 11 by means of a dowel 17 and a thumb nut 18 on a screw stud 19. The stripper 15 is permanently fastened to the block 11 by means of a screw 20. It is provided with a window through which the pins 16 pass after the stripper has come to rest on the paper P during the downward movement of the marking device. The upwardly projecting end flange 22 of the strip er serves as a stop for the marker plate 14 a ter its pins have perforated the paper P.

To the collar 12, which is held on the sleeve 10 by means of a set screw 23, is affixed an arm 24 whose axial projection 25 engages the end of the bar 8, thereby holding the marker in its upper position as long as the bar 8 is at rest. The arm 24 carries a post 26, to which is attached a spring 27 anchored to a post 28 supported by the frame of the machine. When the bar 8 moves forward to allow the clamp 5 to descend on the paper and hold it while a length sufficient for one package is being out off in the wrapping device, the arm 2 of the marking device is released, thereby causin the spring 27 to turn the sleeve 10, thus depressing the pins 16 of the markin plate 14 into engagement with the paper As the paper is depressed by the descending spring 15, it comes to rest upon a perforated paper support 29, which then acts as a ledger plate for the marking ins, the support 29 having a plurality of oles corresponding to all the various combinations of pins on the different marking plates. The support 29 is fastened to the table 4 by means of thumb nuts 30.

As the bar 8 turns back the lever 7 to raise the arm 5 so that the pa er P can start feeding again, it engages t e projection 25 of the arm 24 and pushes the latter back into its rest position, thereby raising the marking plate 14 and pulling the pins 16 from the paper which is held down on the support 29 by the stripping plate 15 until the pins 16 have emerged from it; after which, the spring 15 resumes its normal position and then moves upward with the block 11.

What is claimed is:

1. The combination with a paper clamping device for paper feeding mechanism, of mechanism for moving said device into and out of clamping position, and means controlled by said mechanism for marking paper fed by the paper feeding mechanism.

2. The combination with a paper clamping device for paper feeding mechanism, of mechanism for moving said device into and out of clampin position, and means controlled by sai mechanism for marking paper fed by the paper feedin mechanism, said device including a clamp s aft and said means including a sleeve surrounding said shaft provided with an arm engaging said mechanism.-

3. The combination with a paper clamping device for paper feeding mechanism, of mechanism for moving said device into and out of clampin position, and means controlled by sai mechanism for marking paper fed by the paper feeding mechanism, said device including a clamp shaft and said means including a sleeve surrounding said shaft and provided with an arm engaging said mechanism and with an arm carrying a marking device.

4. The combination with a paper clamping device for paper feeding mechanism, of mechanism for moving said device into and out of clamping position, and means controlled by said mechanism for marking paper fed by the paper feeding mechanism, said device including a clamp shaft and said means includin a sleeve surrounding said shaft and provided with a spring-actuated arm engaging said mechanism and with an arm carrying a marking device.

In testimony whereof, I have signed my name to this specification.

HENRY E. GOERKE.
